What is the highest calorific value of methanol and how to increase the calorific value of methanol

Alcohol oil fuel additive is a high-strength oxidant further developed on the basis of alcohol-based fuel heat stabilizer, which has the functions of one-time combustion, multi-stage reaction and heat multiplication. It can significantly increase the temperature of the furnace, improve the peculiar smell caused by the combustion of inferior methanol, and greatly increase the calorific value and brightness of the fuel, thus solving the technical problem of using methanol fuel in industrial burners! Alcohol-based fuel additives are easily soluble in water, alcoholic liquids, stable in nature, non-flammable, non-corrosive, suitable for long-distance transportation and storage, and provide favorable conditions for the large-scale use of methanol fuel!

1. The unique chemical properties of alcohol-based fuel additives can improve the stability of methanol to the greatest extent. Methanol is a very volatile flammable liquid with very low stability, methanol can change from liquid phase to gas phase at a temperature of 64 degrees, that is, methanol vapor, methanol vapor inhaled by the human body in excess, there will be blindness, blurred vision, headache and chest tightness of poisoning symptoms, which is very harmful to the human body; If methanol vapor accumulates in a confined space, the faint sparks can ignite, which has great potential safety hazards; At the same time, a large amount of evaporation can also reduce the quality of the oil and cause waste. Therefore, the properties of methanol fuel must be changed during production and use, so that it is more stable and safer in production, storage, transportation and use.

The stable chemical properties of methanol fuel additives effectively solve the historical problem of methanol fuel (alcohol-based).

2. Alcohol-based fuel additives are a powerful accelerant, which not only has a strong combustion support effect, but also can keep the chemical reaction stable and avoid the fuel in the furnace The fire is strong and hot, high and low; The various oxidants contained in methanol fuel additives can not only catalyze the decomposition of combustibles in methanol solution at a certain temperature, but also gradually release strong oxygen to support combustion with the increase of temperature. When the combustion temperature reaches 200 degrees, the first-stage reaction begins to decompose and release oxygen, deriving catalysts such as manganese dioxide; When the temperature reaches about 400 degrees, it enters the next stage of reaction, so that more oxidants decompose at high temperatures, release a large amount of oxygen, and the mixed reaction of a variety of super accelerants, so that the fuel oil starts from 200 degrees to about 700 degrees when it enters the furnace temperature, and is in a strong catalytic decomposition reaction, so that the combustibles in the methanol fuel are fully combusted, the fire is fierce, the flame is high, and the fire bed is long, so as to improve the thermal efficiency of the furnace and the purpose of super combustion and energy saving.

Once the fuel of the product is determined, the calorific value cannot be changed. It is better to change to alcohol-free fuel if you want to have a high calorific value.

The calorific value of methanol is 4650 kcal per kilogram.

Methanol is the simplest saturated monoalcohol, molecular weight, boiling point, also known as "wood alcohol" or "wood essence", is a colorless liquid with alcohol odor and volatile, the lowest dose of oral poisoning is about 100mg kg body weight.

It can be lethal when ingested up to 1g kg orally, and is used in the manufacture of formaldehyde and pesticides, as well as as an extractant of organic matter and a denaturant of alcohol, etc., usually prepared by the reaction of carbon monoxide and hydrogen gas.

Precautions for operation:

Closed operation with enhanced ventilation. Operators must be specially trained and strictly follow operating procedures. It is recommended that the operator wear a filtering anti-virus helmet mask (half mask), wear chemical safety glasses, and wear anti-static overalls.

Keep away from fire, heat source slippery, smoking is strictly prohibited in the workplace, use explosion-proof ventilation systems and equipment to prevent vapor leakage into the air in the workplace, control the flow rate during filling, and have a grounding device to prevent static electricity accumulation. <>

How many kcal is the calorific value of methanol, and the calorific value of methanol.

The calorific value of one kilogram of methanol is 4650 kcal kg (4650 kcal per kilogram), which is 1111 kJ kg.

Methanol is the simplest saturated monoalcohol, which was first discovered in dry distilled wood, so it is also called wood alcohol or wood essence.

Methanol is a colorless, alcohol-smelling, volatile liquid. The minimum dose of oral poisoning in humans is about 100 mg kg body weight, which can be fatal if ingested orally.

Methanol is generally used in the manufacture of formaldehyde and pesticides, and is also used as an extractant of organic matter and a denaturant of alcohol. The finished product is usually made by the reaction of carbon monoxide with hydrogen.

Extended Materials. Application of methanol fuel:

The earliest methanol was produced by wood dry distillation, so methanol is also called wood alcohol. The natural free state of methanol is very small, but this method not only wastes wood, but the product contains impurities such as acetone, and it is difficult to remove, so it is not used later.

Coupled with the low flash point of 12° of methanol fuel, it is easy to volatilize at room temperature, while the flash point of diesel 56 is relatively stable and not volatile. The actual cost of use for customers is even higher than that of diesel. Since there is no economic value, it is difficult for a new thing to be popularized.

In addition, improvements have been made in the formula, adding stabilizers, accelerants, etc. In the actual use, the methanol fuel boiler of Luyuan Kemao pays more attention to standardized installation and operation, and strictly controls the volatilization of methanol fuel.

Moreover, we have cooperated with two senior academicians of the Chinese Academy of Sciences who enjoy special allowances to improve the flash point of our green source science and trade methanol fuel. It has now reached 33°, and it will move closer to 50° in the future. Follow-up research is underway and is expected to be achieved soon.

1. Use high-purity methanol with a purity of more than 95%. 2. Increase the oxygen concentration and burn in places with high oxygen concentration. These two methods can accelerate the rate of oxygen dispensation and the original reaction, thereby increasing the temperature of methanol combustion.
